Rewritten parser for GeoJSON files to handle styling

Hi, Torsten,

Thanks!  Will do so, in the next day or so: I need a couple of free
hours...

As far as I could see from the code, the only place this code is
used is for loading user data files.  Other places in the code load
JSON (not necessarily GeoJSON) files but do their own handling -- I
haven't touched that code, and I probably won't need to, as it's
independant of this module.

Yours truly,
